METHOD OF raonucms METALLIC AR'rIcLns' nrnnncrnonnrosrrron.

To all whom 'it may concern:

Be it known that I, FRANK Ionns GIBBS, a subject of His Majesty the Kingof Great Britain'and Ireland, residing at 140 Hurst street, Birmingham;England, manufacturer, have'i'nvented new .and'useful Imrovement's inthe Method of Producing lletallic Articles, by Electrodeposition, ofwhichthe following-is a specification.

This invention consists. of the herein described improved/method ofproducing many ki s of' metallic articles by electrodepo'si 1on on glassor potteryware models, or on models of other non-metallic substances,such for instance as ivory, celluloid, hard w0od, tortoise-shell,vulcanite and jet, on to the surfaces of which, when properly prepared,metals can be deposited and from which the deposit forming the requiredmetal article is afterward removed.

My invention is ap licable to all those metal articles which ave a rimor edge such for instance as tea pots, cofi'ee pots, {"ugs, cups,plates, dishes and all kinds of 0 low-ware articles andto candle sticksvases and the like.

The object of this invention is to form the electro-deposited metalarticle with a rounded channel section or inclosed edge or rim of doublethickness of metal which will be smooth and form a properly finished rimor ed e to the article. As an example I will descn e mylIIVGQtiOEiBJODIlQCtIOn with making a metallic vase and I will refer tothe accompanying drawings on which-7 Figure 1 is a sectiona elevation ofthe glass or other non-metallic or nonorous model which I use in myprocess; 1g.=2 shows the same model wlth an electro-deposit on itsexterior and extending for a a sectional elevation of the complete va$eafter themodel has been removed; F1 l vase showing how the internaloverhangin edge can be closedin to form a hollow ea around the rim;Figs. 5 and 6 are sectional elevations of the bottom of the same vaseshowing how the same maybe" deposited open with a channel section rimand subsequently closed; and Fig. 7 1s a sectional ele- Y vation of. thefoot part of a metal vessel formed with 'a channel section rim in accordance with this invention and closed by a separate metal blank.

Specification of Letters Patent. Application filed February 23, 1909. iSerial No. 479,405.

In making for instance the complete me- Patented Nov. 8,1910.

tallic vase A shown'by Fig. '3, I employ a model B Fig. 1 which is anordinary glass or glazed ,potteryware or other suit-- able non-metallicvase, the exterior sha e of which corresponds with the internals ape" ofthe required vase shown'in Fig. 3, This model is by preference made ofably prepared conducting material of which this invention the conductingmaterial form lass 'orglazed potteryware so as not-to a cot the"electrolyte in the bath, and its'exterior surface is coated with amtallicpaintmf s'ufficient metallic strength'to convey the elec-'tric-current, or is coated with any other suiting the prepared surface 2and which covers 7 the outside of the model B is carried over the topedge of the model to the line 1 in Fig.

1 inside the vase so that the deposited metal will extend from theoutside over the top edge of the 'model anddown to the line 1 in- Figs.1 and 2 and will thus form an inverted channel section rim around thetop of the vase when the model has been broken away or' otherwiseremoved therefrom the upper edge -3 of the vase turning inwardly andforming the inverted channel 4 as in Fi 3. This overhanging edge can ifdesiref be closed in, as in Fig. 4, so as to form' a nice rounded ed e,or this channel 4 can be filled up by caving in it the top rim of theglass or potter ware model which has previously been nic ed around by adiamond at the line 1; or the channel canbe filled in with metallic asteand' the vessel be returned to the but will be deposited over the pasteat what was so that the metal the mouth of the channel thus making anapparently thick solid edge; or the channel 4 "can be filled withsolder, or with wire, or' I with a strip of metal, to strengthen'it, and

with an intnrned edge as shown for instance T in Fig. 5. To accomplishthis the said preared surface will be continued around the cot andfinished at the line 6 in Fig.v 1 so that when the model has beencracked and removed from the de osited exterior the foot of the latterwil have an upturned rim 7 as in Fig. 5 leading wwancentral hole 8 atthe bottom of the vase'which as in Fig. 6 be closed by a metal @1 1! 9be closed down on to the rim of the dish 11 or part which eloses thehollow base and which will then appear to he a part of the same. Afterthis has been done the vessel can be. returned to the hath so as todeposit some more metal around the foot to hide the joint at. 10 so thatthe dish 1 I will then ap-r ear to be an integral part of the Vessel.Vhen the metal or other article, as for instance a vase, is to he formedh v depositing the metal on the inside of the model, then the troughsection rim will turn outwardly instead 'of inwardly as will readily ibe understood as the conducting surt'aee will extend from the interiorof the model over the rim of the same and finish at a definite 5 line onthe outside of the model instead of l inside the same as abovedescribed. The

said channel seetion rim can be similarly formed during the depositingof a metal article which is niade perforated in an ornamental ueisi'gnlike a saw pierced silver article. such for instanee as a sweetmeat dishas will readily he understood.

\Vhat I claim as my imention and desire to secure h Letters Patent is:-

A method of forming a rounded rim at an opening in a metal articleconsisting in continuing the prepared surface of the glass or potteryware model to a definite line on the other side so that when the metalis eleetrodeposited thereon a rim will he formed around the top of thevessel from which the model can he removed. and then filling in the rimwith suitable l'naterial and making .it solid.

In testimony whereof I have signed my name to this speeifieation in thepresent-e of two suhserihing witnesses.
